General Motors announced today it will offer bi-fuel versions of its 2013 Chevrolet Silverado and GMC Sierra pickup trucks that run either on gasoline or natural gas. The two trucks are the 2500 HD (heavy duty) model, and can be ordered in rear-wheel or four-wheel drive and with a standard or long...

For years, the great and the good of Hollywood have helped encourage people to ditch gas guzzlers by turning up to red-carpet events and driving around Beverly Hills in an eclectic mix of trendy eco-cars. But when those cars are traded in for the latest, greenest model, or perhaps swapped for...

If you choose to run your car on an alternative fuel or electricity, it's not always as easy to find somewhere to refuel or recharge as it might be with a normal gasoline vehicle. Luckily, you have technology on your side in the modern age. So below you'll find the best five ways of locating that...

Ferraris aren't typically known for their green credentials. In fact, they tend to be known for everything but green credentials: High performance, for example. High-revving V-8 and V-12 engines. Being painted very, very red. Not being painted green. Most methods of extracting greater power from...

It's pretty difficult to feel sorry for oil companies. Why should we? They're in control of a resource we all depend upon, one way or another, and can essentially charge whatever they like for it. As a result, they make massive profits every year. Nobody pities the rich guy. But maybe we feel a...

For first responders, helping deal with the aftermath of a car crash is a common occurrence. But while dealing with crashed gasoline cars is an everyday event for firefighters, police officers and paramedics, crashes involving plug-in, hydrogen and other green cars are relatively rare. As a...

Natural gas has forever been a "nearly" fuel. While offering several advantages over gasoline or diesel, such as low cost of refueling, HOV-lane stickers in California and cleaner running, the disadvantages are even greater. One of those has been the availability of natural gas, limiting its...

When the U.S. Congress adjourned for the holidays on Friday, December 23, its departure sealed the fate of subsidized ethanol production. During its session, the Congress did not renew a tax break for U.S. production of corn-based ethanol that had become increasingly unpopular across a wide area of...

Despite millions of dollars of commitment from automakers like Ford and General Motors, finding somewhere to fill your flex-fuel car with E85 is now officially harder than finding somewhere to recharge a plug-in car. In fact, according to Bloomberg, the number of electric car charging stations in...

Honda has been the only carmaker to offer a natural-gas powered passenger car, and they've done it quietly in a handful of states for more than a decade. But with the arrival of an all-new Civic this year, the company will make the 2012 Honda Civic Natural Gas available through selected dealers...

Natural gas vehicles aren't particularly common on U.S. roads, and with relatively cheap and plentiful gasoline, it's fairly clear why. Pumps are few and far between and only the 2012 Honda Civic Natural Gas gives private buyers an option over gasoline or diesel. If you had the chance to fill at...

Which alternate vehicle or fuel do you know least about? You've almost surely heard about hybrids. You may have seen ethanol, even biodiesel, debated in the news. And if you read this site, you're likely to know that cars that plug into grid power to recharge their battery packs are now on sale...

Honda released the bulk of its 2012 Civic range this spring, but one model lagged behind: the Civic Natural Gas, the all-new version of what had been called the Civic GX. As the new name indicates, the 2012 Honda Civic Natural Gas runs solely on compressed natural gas. It's the only natural-gas...

Combine a whole bunch of parts from motorcycles, go-karts, industrial machinery, and even generators, and what do you get? In John Petsche's case, he not only built a motorcycle that runs on store-bought vegetable oil, he managed to take home a world speed record for the 350cc Alternate Fuel class...

The Ford Transit Connect, in both gasoline and CNG versions, has begun deployment for taxi duty from coast to coast.

In the middle of his much-publicized bus tour into the nation's agricultural heartland on Tuesday, President Obama announced a new initiative to kickstart the U.S. biofuel industry, which among other things would create more jobs for rural communities in the biofuel production chain. The...

The World Solar Challenge pits the cutting edge of aerodynamics and solar power systems against the great outback of the land down under.

We don't hear so much about hydrogen fuel-cell vehicles these days. Just five years ago, before the announcement of either the 2011 Nissan Leaf battery electric car or the 2011 Chevy Volt range-extended electric, several auto companies were in the process of developing test fleets of...

The American Le Mans Series is taking steps to promote renewable fuels and alternative fuel sources. Series president Scott Atherton is out to prove that racing can produce environmental benefits.

Ah, ethanol, that most political of alternative fuels. Farmers love it, deficit hawks hate it, automakers want it for flex-fuel CAFE credits but nowhere else, and environmentalists only want it if it doesn't suck up food supplies, use too much water, or worsen the carbon balance. Yesterday, EPA...
